Abstract
BACKGROUND Autologous flaps may have superior outcomes when compared to implant breast reconstruction in patients with obesity. To date, no published review has illustrated the superiority of autologous to implant-based reconstruction in this study group in terms of aesthetics outcomes and surgical complications. METHODS A systematic search was conducted on PubMed, Cochrane, Google Scholar, and Embase from inception to December 31, 2020. Studies comparing the outcomes (patient satisfaction and complications) of autologous versus implant-based reconstruction in patients with BMI > 30 were selected. RESULTS The search yielded 1633 articles, of which 76 were assessed in full text. A total of 12 articles fit inclusion for qualitative review; of them, 7 were meta-analyzed. Autologous reconstruction had a lower incidence of infection (OR 0.74 [95% CI 0.59, 0.92]), hematoma/seroma formation (OR 0.34 [95% CI 0.23, 0.49]), and reconstructive failure (OR 0.47 [95% CI 0.36, 0.62]), but not skin necrosis (OR 0.95 [95% CI 0.73, 1.25]) or wound dehiscence (OR 1.03 [95% CI 0.72, 1.49]) when compared to implant-based reconstruction. Deep vein thrombosis (DVT) and pulmonary embolism occurred more frequently with autologous versus alloplastic reconstruction (OR 2.21 [95% CI 1.09, 4.49] for DVT and OR 2.49 [95% CI 1.13, 5.48] for PE). BREASTQ scores were higher for the autologous breast reconstruction when compared to implant-based group, but failed to reach significance (p value >0.05). CONCLUSION The current evidence in the literature suggests that autologous breast reconstruction has lower surgical complication rate when compared to implant-based reconstruction at the expense of higher risk of thrombotic complications for patients with BMI > 30.

Abstract
Objective The present study is a phase I/IIa non-randomized, open-label study to evaluate safety and efficacy of a single, intravenous infusion of autologous, adipose-derived mesenchymal stem cells (adMSCs) over a period of 52 weeks, in patients with active rheumatoid arthritis (RA).
Methods 15 eligible RA patients aged 18–65 years were enrolled and followed up at weeks 4, 12, 26 and 52 after receiving a single intravenous dose of 2 × 108 adMSCs. Efficacy was examined using American College of Rheumatology (ACR66/68 score) criteria for swollen and tender joint counts (S/TJC), and serum TNF-α, IL-6, CRP, and ESR levels. Safety endpoints included measures of hematologic, hepatic, and renal function. Results ACR66/68 scores for both S/TJC showed significant improvements with large effect sizes (ES) at week 52 vs baseline (p < 0.01, ES = 0.83 and p < 0.001, ES = 0.93 respectively). Medium to large ES were also obvious for ACR66/68 scores measured at other timepoints. Levels of inflammatory markers, TNF-α, IL-6 and ESR remained unchanged compared to baseline. However, a difference in CRP levels with a small effect size was observed at week 4 (p = 0.229, ES = 0.33) with further improvement at week 52 (p = 0.183, ES = 0.37). Post-intervention, levels of hematologic, hepatic, and renal function remained largely unchanged (p > 0.05). No acute or long-term serious adverse events (AEs) occurred. Conclusions The results indicated that a single, intravenous administration of autologous adMSCs is safe and efficacious for improvement in joint function in patients with active RA. Data from the current study supports the exploration of ad-MSCs as a therapeutic intervention for RA. Trial Registration Clinical trial registration number: NCT03691909. Registered September 27, 2018- Retrospectively registered (https://clinicaltrials.gov/show/NCT03691909).

Abstract
BACKGROUND hypospadias is one of the most widespread male congenital anomalies, occurring in 1:250 to 1:300 live births. Several repair techniques have been developing to improve the outcomes. PURPOSE a randomized prospective controlled study was adopted to evaluate effectiveness of autologous platelet gel in healing promotion and improving the outcomes of hypospadias repair. METHODS thirty children who aged between 6 months and 12 years were recruited and subdivided into two groups; group A had tubularized incised plate (TIP) repair with autologous platelet gel application and group B had TIP repair without autologous platelet gel. RESULTS there was no significant difference in duration of operation between both groups. All patients in groups A and B had slit-like meatus shape in the distal glans. While all those of group A had one urine stream, yet only 11 of group B had one. There were complications that happened exclusively in group B such as spray stream (27%) and fistula (20%). Whereas other complications occurred insignificantly more in group B than in A including meatal stenosis (53 versus 27%), glans dehiscence, (20 versus 7%), bleeding (33 versus 13%), infection (33 versus 27%), edema (27% versus13), respectively. The incidence of skin necrosis was equal in both groups. CONCLUSION autologous platelet gel usage in TIP hypospadias repair can be a reliable technique to promote wound healing, and to limit of postoperative surgical complications.

Abstract
INTRODUCTION : Hematopoietic stem cell transplantation (HSCT) is a critical therapeutic procedure in blood diseases, and the investigation of HSCT data can provide valuable information. Machine learning (ML) techniques are novel and useful data analysis tools that have been applied in many studies to predict HSCT survival and estimate the risk of transplantation. AREAS COVERED : A systematic review was performed with a search of PubMed, Science Direct, Embase, Scopus, and the European Society for Blood and Marrow Transplantation, the Center for International Blood and Marrow Transplant Research, and the American Society for Transplantation and Cellular Therapy publications for articles published by September 2020. EXPERT OPINION : After investigating the results, 24 papers that met eligibility criteria were included in this study. The applied ML algorithms with the highest performance were Random Survival Forests (AUC=0.72) for survival-related, Random Survival Forests and Logistic Regression (AUC=0.77) for mortality-related, Deep Learning (AUC=0.8) for relapse, L2-Regularized Logistic Regression (AUC=0.66) for Acute-Graft Versus Host Disease, Random Survival Forests (AUC=0.88) for sepsis, Elastic-Net Regression (AUC=0.89) for cognitive impairment, and Bayesian Network (AUC=0.997) for oral mucositis outcome. This review reveals the potential of ML techniques to predict HSCT outcomes and apply them to developing clinical decision support systems.

Abstract
Mesenchymal stromal cells (MSCs) express a wide range of properties anticipated to be beneficial for treating genetic, mechanical, and age-related degeneration in diseases such as osteoarthritis (OA). Although contemporary conservative management of OA is successful in many patients with mild-moderate OA, it often fails to improve symptoms in many patients who are not a candidate for any surgical management. Further, existing conservative treatment strategies do not prevent the progression of the disease and therefore fail to provide a long-term pain-free life. On the other hand, tremendous progress has been taking place in the exciting field of regenerative medicine involving MSCs (autologous and allogeneic), with promising translation taking place from basic science to the bedside. In this review, we comprehensively discuss the potential role of MSCs in treating OA, both autologous and off-the-shelf, allogeneic stem cells. Further, newer therapies are in the offing to treat OA, such as exosomes and growth factors.

Abstract
Deep plantar fissures are a common, painful condition, which are often recalcitrant to multiple modalities. Autologous platelet-rich fibrin is a reservoir of supraphysiological concentration of platelets housing various growth factors shown to accelerate wound healing. This unique form factor affords a novel advantage of its ability to be applied over and within these fissures under occlusion. We report the innovative use of disposable syringes to fashion platelet-rich fibrin casts for management of these deeper fissures.

Abstract
BACKGROUND The reamer irrigator aspirator (RIA) is a relatively recent device that is placed in the medullary canal of long bones to harvest a large volume of bone marrow, which is collected in a filtered canister. This study compares outcomes and complications of the RIA versus a traditional iliac crest bone graft (ICBG) for the treatment of bone defects. METHODS This meta-analysis was conducted according to the PRISMA guidelines. The Embase, Google Scholar, PubMed, and Scopus databases were accessed in June 2021. All clinical trials comparing the RIA and ICBG with a minimum of 6 months follow-up were included. RESULTS Data from 4819 patients were collected. The RIA group demonstrated lower site pain (P < 0.0001), fewer infections (P = 0.001), and a lower rate of adverse events (P < 0.0001). The ICBG group demonstrated a greater rate of bone union (P < 0.0001). There was no difference between groups in VAS (P = 0.09) and mean time to union (P = 0.06). CONCLUSION The current evidence supports the use of the RIA, given its low morbidity and short learning curve.

Abstract
Thiotepa, an antineoplastic ethylenimine alkylating agent that can penetrate the central nervous system, was recently approved in Japan as high-dose chemotherapy prior to autologous hematopoietic stem cell transplantation (HSCT) for patients with malignant lymphoma. To further evaluate the safety and efficacy of thiotepa, a multicenter, open-label, non-comparative, expanded access program was undertaken in Japan, including a larger population of Asian patients with malignant lymphoma. Intravenous thiotepa (200 mg/m2/day) was administered over 2 h on days -4 and -3 before scheduled HSCT, plus intravenous busulfan (0.8 mg/kg) over 2 h every 6 h on days -8, -7, -6 and -5. In the safety analysis population (N = 51), 25 patients (49.0%) had primary central nervous system lymphomas. The most common treatment-emergent adverse event was febrile neutropenia (49/51 [96.1%]). No unexpected safety events were observed, and no event resulted in death or treatment modification. Forty-seven patients (92.2%) had engraftment (neutrophil count ≥ 500/mm3 for three consecutive days after bone-marrow suppression and HSCT). The survival rate at day 100 post-transplantation was 100%. These data confirm the safety of thiotepa prior to autologous HSCT for patients with malignant lymphoma. Trial registration: JapicCTI-173654.

Abstract
BACKGROUND Defect treatment with tendon autograft in osteochondral lesions has been published in the literature with an experimental study in dogs. To demonstrate that it is possible to treat knee osteochondral lesions with the technique of autologous tendon transplantation.
AIM To evaluate the clinical and radiological results of patients with knee osteochondral lesions who were treated with autologous tendon transplantation.
METHODS Twenty patients (22 knees) with osteochondritis dissecans (OCD) lesions involving the knee were treated with autologous tendon transplantation between 2005-2018. All lesions were International Cartilage Repair Society grade IV. All patients were evaluated clinically at final follow-up with knee injury and osteoarthritis outcome score (KOOS); and radiologically with magnetic resonance observation and cartilage repair tissue (MOCART) and Kellgren-Lawrence (KL) classification.
RESULTS A total of 20 patients (22 knees) with a mean age of 25.5± 6.8 years were included. The average defect size was 4.2 ± 2.1 cm2, and the average defect depth was 0.9 ± 0.4 cm. Total KOOS score was preoperatively 29.4 ± 5.5 and was later found to be 81.5 ± 5.9 after an average of 68.7 ± 37.7 mo follow-up. The mean MOCART score was 56.2 ± 10.7. Preoperatively, all of the patients had KL grades of 0–1; during the follow-up period, 80% of the patients showed no radiological progress of osteoarthritis. Patients with less than 4 cm2 lesion had statistically significantly better overall KOOS than patients whose more than 4 cm2 lesion, particularly in sport and quality of life subscales.
CONCLUSION The autologous tendon transplantation is a single-step, safe, simple, cost-effective method for the treatment of knee OCD with satisfactory clinical and radiological outcomes, particularly in patients with less than 4 cm2 lesion.

Abstract
To manage the deficient nasal dorsum, a thorough knowledge of dorsal augmentation techniques should be mastered by the rhinoplasty specialist. Indications for dorsal augmentation may arise in both primary and revision rhinoplasty presentations. To direct operative planning, a complete facial analysis, noting the importance of maintaining overall nasofacial balance, is essential. An array of techniques, including autologous and nonautologous (ie, allogeneic and synthetic) sources, have been used globally-each carrying its own advantages and disadvantages. The authors believe autologous grafts to be the optimal source for dorsal augmentation because of their biocompatibility and ability to produce natural and long-lasting outcomes.

Abstract
The primary goal of this systematic review article was to provide an outline of the use of diabetic autologous adipose-derived mesenchymal stem cells (DAAD-MSCs) in the treatment of wounds and ulcers in animal models and patients with diabetes mellitus (DM). The secondary goal was to present the outcomes of pretreatment of diabetic adipose-derived mesenchymal stem cells (DAD-MSCs) with probable different agents in the treatment of diabetic foot ulcers (DFUs) and wounds. In view of possible clinical applications of AD-MSC-mediated cell therapy for DFUs, it is essential to evaluate the influence of DM on AD-MSC functions. Nevertheless, there are conflicting results about the effects of DAAD-MSCs on accelerating wound healing in animals and DM patients. Multistep research of the MEDLINE, PubMed, Embase, Clinicaltrials.gov, Scopus database, and Cochrane databases was conducted for abstracts and full-text scientific papers published between 2000 and 2020. Finally, 5 articles confirmed that the usage of allogeneic or autologous AD-MSCs had encouraging outcomes on diabetic wound healing. One study reported that DM changes AD-MSC function and therapeutic potential, and one article recommended that the pretreatment of diabetic allogeneic adipose-derived mesenchymal stem cells (DAlD-MSCs) was more effective in accelerating diabetic wound healing. Recently, much work has concentrated on evolving innovative healing tactics for hastening the repair of DFUs. While DM alters the intrinsic properties of AD-MSCs and impairs their function, one animal study showed that the pretreatment of DAlD-MSCs in vitro significantly increased the function of DAlD-MSCs compared with DAlD-MSCs without any treatment. Preconditioning diabetic AD-MSCs with pretreatment agents like photobiomodulation (PBM) significantly hastened healing in delayed-healing wounds. It is suggested that further animal and human studies be conducted in order to provide more documentation. Hopefully, these outcomes will help the use of DAAD-MSCs plus PBM as a routine treatment protocol for healing severe DFUs in DM patients.

Abstract
Large bone defects resulting from musculoskeletal tumours, infections, or trauma are often unable to heal spontaneously. The challenge for surgeons is to avoid amputation, and provide the best functional outcomes. Allograft, vascularized fibular or iliac graft, hybrid graft, extracorporeal devitalized autograft, distraction osteogenesis, induced-membrane technique, and segmental prostheses are the most common surgical strategies to manage large bone defects. Given its optimal osteogenesis, osteoinduction, osteoconduction, and histocompatibility properties, along with the lower the risk of immunological rejection, autologous graft represents the most common used strategy for reconstruction of bone defects. However, the choice of the best surgical technique is still debated, and no consensus has been reached. The present study investigated the current reconstructive strategies for large bone defect after trauma, infections, or tumour excision, discussed advantages and disadvantages of each technique, debated available techniques and materials, and evaluated complications and new perspectives.

Abstract
PURPOSE Face rejuvenation procedures with injectable agents continue to gain popularity. Nowadays, a variety of commercial products are available as filler material. Ideal fillers should be inexpensive, easily obtainable, nontoxic, and biocompatible. The aim of this study is to report a clinical perspective for an appropriate, feasible, and inexpensive protocol of a stable, autologous biological filler for facial volume restoring without any commercial kits. METHODS Eight patients were investigated who underwent facial injection with ABC filler. Eleven ml of whole blood was placed in standard tubes containing anticoagulant and for each patient, 8 tubes were prepared. After the centrifugation at 1630 xg for 5 minutes, the upper plasma was taken, calcium was added and cooled. After the addition of vitamin C, the syringes were incubated at 85 °C for 10 minutes. The autologous biological material obtained was used as filling material. For comparison, FACE-Q satisfaction questionnaires were used before and after the procedure. RESULTS All patients were followed up for a minimum of 4 months. No major complications were recorded. The patient-reported FACE-Q satisfaction and FACE-Q quality of life pre- and post-procedure results showed statistically significant improvement (p < 0.05). Overall satisfaction with the outcome was 89.12 ± 16.73 (range 55-100). CONCLUSIONS ABC filler can be seen as a reliable, inexpensive, and easily obtainable material to restore facial volume with increased patient satisfaction and quality of life scores. We believe that our study will be encouraging to the application of autologous biological fillers for further clinical and scientific studies.

Abstract
In 2006, the induced pluripotent stem cell (iPSC) was presented to the world, paving the way for the development of a magnitude of novel therapeutic alternatives, addressing a diverse range of diseases. However, despite the immense cell therapy potential, relatively few clinical trials evaluating iPSC-technology have actually translated into interventional, clinically applied treatment regimens. Herein, our aim was to determine trends in globally conducted clinical trials involving iPSCs. Data were derived both from well-known registries recording clinical trials from across the globe, and databases from individual countries. Comparisons were firstly drawn between observational and interventional studies before the latter was further analyzed in terms of therapeutic and nontherapeutic trials. Our main observations included global distribution, purpose, target size, and types of disorder relevant to evaluated trials. In terms of nontherapeutic trials, the USA conducted the majority, a large average number of participants-187-was included in the trials, and studies on circulatory system disorders comprised a slightly higher proportion of total studies. Conversely, Japan was the frontrunner in terms of conducting therapeutic trials, and the average number of participants was much lower, at roughly 29. Disorders of the circulatory, as well as nervous and visual systems, were all studied in equal measure. This review highlights the impact that iPSC-based cell therapies can have, should development thereof gain more traction. We lastly considered a few companies that are actively utilizing iPSCs in the development of therapies for various diseases, for whom the global trends in clinical trials could become increasingly important.

Abstract
INTRODUCTION Autologous breast reconstruction has evolved from more morbid procedures that sacrificed the abdominal muscle (the TRAM or transverse rectus abdominus muscle flap) to "perforator" flaps. Commercial insurers recognized the higher technical demand of perforator flaps by creating procedural codes with higher professional fees. This study examined whether procedure code discrepancies between insurance payers disproportionally incentivize perforator flaps among the commercially insured. METHODS Autologous breast reconstructions identified from the National Inpatient Sample (NIS) were subdivided into microvascular perforator (85.74, 85.75, 85.76), microvascular TRAM (85.73), and pedicled TRAM flaps (85.72). Demographics, comorbidities and access to care were compared. A logistic regression comparing microvascular reconstructions only was used to identify predictors for perforator flap reconstruction. RESULTS A total of 66,968 cases of autologous breast reconstruction were identified. Perforator flaps were more likely among the commercially insured (p < 0.001) and higher insurance quartiles (p < 0.001).When comparing microvascular reconstruction, perforator flaps were 1.72 (p < 0.001) times more likely among the commercially insured. As compared to the lowest income quartile, the fourth quartile had an odds ratio of 1.36 (p < 0.001) for perforator flap reconstruction. CONCLUSION The presence of a separate perforator flap billing code among the commercially insured may be exacerbating existing socioeconomic disparities in breast cancer reconstruction.

Abstract
OBJECTIVES Besides the uncertainty about colorectal cancer stem cell (CCSC) markers, isolating, purifying, and enriching CCSCs to produce CCSC vaccines is highly challenging. However, allogeneic vaccines developed from CRC cell lines can provide universal, comprehensive, inexpensive, simple, and fast approach to cancer treatment. MATERIALS AND METHODS CCSCs were isolated from human CRC tissue using the in vitro sphere formation assay and then characterized through gene expression analysis, in vivo and in vitro tumor formation assay, karyotyping, and surface marker detection. Subsequently, CCSCs and two CRC cell lines (HT-29 and SW-480) were inactivated with cisplatin (CDDP) and administrated as vaccines to the three groups of athymic C57BL/6 nude mice. Afterward, tumorigenesis was challenged with HT-29 cells. The antitumor effect of vaccines was evaluated by tumor and spleen examination and immune response analysis. The cytotoxic activity of splenocytes and serum levels of TGF-β and IFN-γ were measured by Calcein-AM cytotoxicity assay and enzyme-linked immunosorbent assay (ELISA), respectively. RESULTS The results of gene expression analysis showed that CCSCs are CD44+CD133-LGR5-. All vaccinations resulted in decreased tumor growth, spleen enlargement, enhanced serum level of IFN-γ and TGF-β, and increased cytotoxic activity of natural killer (NK) cells. The antitumor efficacy of the CCSC vaccine was not more than CRC cell line-based vaccines. Interestingly, the allogeneic SW-480 vaccine could effectively inhibit tumorigenesis. CONCLUSION Despite the great challenge in developing CCSC vaccines, allogeneic vaccines based on CRC cell lines can efficiently induce antitumor immunity in CRC.

Abstract
Objectives The use of fat grafts in maxillofacial sculpturing is currently a common technique. Unlike fillers, autologous fats unite with facial tissues, but long-term results may still be unsatisfactory. Sharing long-term follow-ups can be helpful in making outcomes more predictable. Materials and Methods The data from patients who were admitted from 2014 to 2016 for fat augmentation were collected. In all cases, fat grafts were injected by blunt cannula using a tunneling technique in different planes. A fan shape order for the malar, periorbital, nasolabial fold, mandibular angle and body, and perioral area was established. Results Autologous fat was used for different sites of the maxillofacial regions. Of 15 patients, two patients were not satisfied due to fat graft resorption. For this, further injections were performed six months after the first injection using preserved fat grafts. One patient continued to be dissatisfied. There were no other complications related to fat transplants. Conclusion Fat transplantation is a safe, reliable, and non-invasive method for facial contour and facial soft tissue defect restoration. Additional methods such as mesenchymal stem cells along with fat injection increase the survival rate of transferred fat.

Abstract
BACKGROUND There is great uncertainty regarding the practice of immediate autologous breast reconstruction (IBR) when post-mastectomy radiotherapy (PMRT) is indicated. Plastic surgery units differ in their treatment protocols, with some recommending delayed breast reconstruction (DBR) following PMRT. IBR offers significant cosmetic and psychosocial benefits; however, the morbidity of flap exposure to radiation remains unclear. OBJECTIVE The aim of this review was to comprehensively analyze the existing literature comparing autologous flaps exposed to PMRT and flaps with no radiation exposure. METHODS A comprehensive search in MEDLINE, EMBASE and CENTRAL databases was conducted in November 2020. Primary studies comparing IBR with and without adjuvant PMRT were assessed for the following primary outcomes: clinical complications, observer-reported outcomes and patient-reported satisfaction rates. Meta-analysis was performed to obtain pooled risk ratios of individual complications. RESULTS Twenty-one articles involving 3817 patients were included. Meta-analysis of pooled data gave risk ratios for fat necrosis (RR = 1.91, p < 0.00001), secondary surgery (RR = 1.62, p = 0.03) and volume loss (RR = 8.16, p < 0.00001) favoring unirradiated flaps, but no significant difference was observed in all other reported complications. The no-PMRT group scored significantly higher in observer-reported measures. However, self-reported aesthetic and general satisfaction rates were similar between groups. CONCLUSION IBR should be offered after mastectomy to patients requiring PMRT. The higher risks of fat necrosis and contracture appear to be less clinically relevant as corroborated by positive scores from patients developing these complications. Preoperative and intraoperative measures should be taken to further optimize reconstruction and mitigate post-radiation sequel. Careful management of patients' expectations is also imperative.

Abstract
BACKGROUND There are many questions that remain unanswered regarding outcomes following cranioplasty including the timing of cranioplasty following craniectomy as well as the material used. OBJECTIVE To establish and evaluate 30-d outcomes for all cranial reconstruction procedures in the United Kingdom (UK) and Ireland through a prospective multicenter cohort study. METHODS Patients undergoing cranioplasty insertion or revision between June 1, 2019 and November 30, 2019 in 25 neurosurgical units were included. Data collected include demographics, craniectomy date and indication, cranioplasty material and date, and 30-d outcome. RESULTS In total, 313 operations were included, consisting of 255 new cranioplasty insertions and 58 revisions. Of the new insertions, the most common indications for craniectomy were traumatic brain injury (n = 110, 43%), cerebral infarct (n = 38, 15%), and aneurysmal subarachnoid hemorrhage (n = 30, 12%). The most common material was titanium (n = 163, 64%). Median time to cranioplasty was 244 d (interquartile range 144-385), with 37 new insertions (15%) within or equal to 90 d. In 30-d follow-up, there were no mortalities. There were 14 readmissions, with 10 patients sustaining a wound infection within 30 d (4%). Of the 58 revisions, the most common reason was due to infection (n = 33, 59%) and skin breakdown (n = 13, 23%). In 41 (71%) cases, the plate was removed during the revision surgery. CONCLUSION This study is the largest prospective study of cranioplasty representing the first results from the UK Cranial Reconstruction Registry, a first national registry focused on cranioplasty with the potential to address outstanding research questions for this procedure.

Abstract
Total pancreatectomy (TP) is a procedure weighed down not only by postoperative morbidity and mortality but also by long-term effects as a consequence of endocrine and exocrine pancreatic insufficiency. While the latter is now managed quite effectively with pancreatic enzyme replacement therapy, the former remains a challenge. The diabetes resulting after TP, with the complete loss of endogenous insulin and contraregulatory hormones, is characterized by important glycemic variations and is, therefore, frequently referred to as "brittle diabetes". One method to reduce the impact of brittle diabetes in patients undergoing TP is the re-infusion of autologous pancreatic islets isolated from the resected pancreas. Indications to islet autotransplantation (IAT), originally described for patients undergoing TP for chronic pancreatitis, have since been extended to selected patients with other benign and malignant diseases of pancreas. This review recaps on the literature regarding long-term postoperative complications, their impact on quality of life after TP and the role of IAT.

Abstract
Current international guidelines recommend routinely vaccinating haematopoetic stem cell transplant (HSCT) recipients. Despite significant infection-related mortality following autologous HSCT, routine vaccination programmes (RVP) completion is poor. For recovered HSCT recipients, it is uncertain whether catch-up vaccination remains worthwhile years later. To determine potential susceptibility to vaccine preventable infections, we measured antibody titres in 56 patients, a median of 7 years (range 0-29) following autologous HSCT, who had not completed RVP. We found that almost all participants had inadequate titres against diphtheria (98.2%) and pneumococcal infection (100%), and a significant proportion had inadequate titres against measles (34.5%). Of those subsequently vaccinated according to available guidelines, many mounted adequate serological responses. These data suggest a pragmatic catch-up approach for autologous HSCT recipients who have not completed RVP is advisable, with universal vaccination against some pathogens (e.g. Streptococcus pneumoniae and diphtheria) and serologically-guided approaches for others (e.g. measles and varicella zoster virus).

Abstract
INTRODUCTION Secondary lymphedema is the abnormal collection of lymphatic fluid within subcutaneous structures. Patients with lymphedema suffer a low quality of life. In our study, we aim to provide a systematic review of the current data on patient outcomes regarding breast cancer-related lymphedema (BCRL), and the most prevalent reconstructive techniques. METHODS A PubMed (MEDLINE) and Scopus literature search was performed in September 2020. Studies were screened based on inclusion/exclusion criteria. The protocol was registered at the International Prospective Register of Systematic Reviews (PROSPERO), and it was reported in line with the PRISMA statement (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). RESULTS The search yielded 254 papers from 2010 to 2020. 67 were included in our study. Lymphaticovenous anastomosis (LVA)-a minimally invasive procedure diverting the lymph into the dermal venous drainage system-combined with postoperative bandaging and compression garments yields superior results with minimal donor site lymphedema morbidity. Vascularized lymph node transfer (VLNT)-another microsurgical technique, often combined with autologous free flap breast reconstruction-improves lymphedema and brachial plexus neuropathies, and reduces the risk of cellulitis. The combination of LVA and VLNT or with other methods maximizes their effectiveness. Vascularized lymph vessel transfer (VLVT) consists of harvesting certain lymph vessels, sparing the donor site's lymph nodes. CONCLUSION Together with integrated lymphedema therapy, proper staging, and appropriate selection of procedure, safe and efficient surgical techniques can be beneficial to many patients with BCRL.

Abstract
BACKGROUND A third of breast cancer patients require mastectomy. In some high-risk cases postmastectomy radiotherapy (PMRT) is indicated, threatening reconstructive complications. Several PMRT and reconstruction combinations are used. Autologous flap (AF) reconstruction may be immediate (AF→PMRT), delayed-immediate with tissue expander (TE [TE→PMRT→AF]) or delayed (PMRT→AF). Implant-based breast reconstruction (IBBR) includes immediate TE followed by PMRT and conversion to permanent implant (PI [TE→PMRT→PI]), delayed TE insertion (PMRT→TE→PI), and prosthetic implant conversion prior to PMRT (TE→PI→PMRT). AIM Perform a network metanalysis (NMA) assessing optimal sequencing of PMRT and reconstructive type. METHODS A systematic review and NMA was performed according to PRISMA-NMA guidelines. NMA was conducted using R packages netmeta and Shiny. RESULTS 16 studies from 4182 identified, involving 2322 reconstructions over three decades, met predefined inclusion criteria. Studies demonstrated moderate heterogeneity. Multiple comparisons combining direct and indirect evidence established AF-PMRT as the optimal approach to avoid reconstructive failure, compared with IBBR strategies (versus PMRT→TE→PI; OR [odds ratio] 0.10, CrI [95% credible interval] 0.02 to 0.55; versus TE→PMRT→PI; OR 0.13, CrI 0.02 to 0.75; versus TE→PI→PMRT OR 0.24, CrI 0.05 to 1.05). PMRT→AF best avoided infection, demonstrating significant improvement versus PMRT→TE→PI alone (OR 0.12, CrI 0.02 to 0.88). Subgroup analysis of IBBR found TE→PI→PMRT reduced failure rates (OR 0.35, CrI 0.15-0.81) compared to other IBBR strategies but increased capsular contracture. CONCLUSION Immediate AF reconstruction is associated with reduced failure in the setting of PMRT. However, optimal reconstructive strategy depends on patient, surgeon and institutional factors. If IBBR is chosen, complication rates decrease if performed prior to PMRT. PROSPERO REGISTRATION CRD 42020157077.

Abstract
Since 2019, all vaginal mesh implants were removed from the market. Since, surgeons have only the autologous technique left to treat prolapse by vaginal route. The anterior sacrospinofixation is an alternative technique to treat vaginally apical prolapses. We have divided the anterior sacrospinous ligament fixation technique into 10 surgical steps: exposure, infiltration, vaginal incision, vesico-vaginal dissection, paravesical dissection, sacrospinous ligament suture (two passage in the SSL on each side, using a suture-capturing device), vaginal fixation, vaginal closure, sacrospinous ligament fixation and final closure. We have performed more than 50 ASSF. This technique is not very well known, and the surgeons are more used to approach the SSL by posterior way. We have included a video of the procedure and an anatomical drawing exhibiting the dissection of the SSL without eyes control. We also added tips and tricks to easily apprehend this new technique. The anterior approach seems to has several advantages compared to the traditional posterior technique. We want to share such a video on showing how to approach the paravesical fossa anteriorly without eyes control.

Abstract
BACKGROUND Stromal vascular fraction (SVF), derived enzymatically or mechanically from adipose tissue, contains a heterogenous population of cells and stroma, including multipotent stem cells. The regenerative capacity of SVF may potentially be adapted for a broad range of clinical applications, including the healing of acute cutaneous wounds. OBJECTIVE To evaluate the available literature on the efficacy and safety of autologous adipose-derived stromal vascular fraction (SVF) for the treatment of acute cutaneous wounds in humans. METHODS A systematic review of the literature utilizing MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials was performed to identify published clinical trials of autologous adipose-derived SVF or similar ADSC-containing derivatives for patients with acute cutaneous wounds. This was supplemented by searches for ongoing clinical trials through ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform. RESULTS 872 records were initially retrieved. Application of inclusion and exclusion criteria yielded 10 relevant studies: two completed non-randomized controlled trials and eight ongoing clinical trials. Both completed studies reported a statistically significant benefit in percentage re-epithelialization and time to healing for the SVF treatment arms. Safety information for SVF was not provided. Ongoing clinical trials were assessing outcomes such as safety, patient and observer reported scar appearance, wound healing rate, and wound epithelization. CONCLUSION In the context of substantial limitations in the quantity and quality of available evidence, the existing literature suggests that SVF may be a useful treatment for acute cutaneous wounds in humans. More clinical trials with improved outcome measures and safety assessment are needed.

Abstract
IMPORTANCE Nonscarring alopecia, including androgenetic alopecia and alopecia areata, are common and can negatively impact quality of life. Recent clinical studies have investigated autologous, adipose-derived stromal vascular fraction (SVF) as a potentially beneficial treatment option. OBJECTIVE To assess the available evidence on the utility and safety of SVF for nonscarring alopecia. EVIDENCE REVIEW A systematic review of the literature was performed using MEDLINE (PubMed), Embase, and CENTRAL from inception to November 2020. Included articles were prospective, observational or interventional studies of SVF for nonscarring alopecia in humans. FINDINGS Six studies of 188 patients were identified, including three randomized controlled trials. There were no reported severe adverse events. All studies found improved hair density with SVF compared to control or pre-treatment baseline. One study reported that improvement in hair density varied based on time for follow-up, severity of hair loss, and concentration of adipose-derived stem cells (ADSCs) within the SVF. Two studies reported an increase in hair diameter from baseline, and two studies reported an improvement in hair pull test outcomes. CONCLUSIONS AND RELEVANCE SVF may be safe and effective for nonscarring alopecia in the appropriate patients. Hair loss severity, method of SVF preparation and frequency of treatment, and adjunctive therapies may be important considerations for treatment success. Additional studies evaluating appropriate patient selection and treatment methods are needed.

Abstract
OBJECTIVE Over the past decade numbers of bilateral mastectomy have increased steadily. As a result, bilateral breast reconstruction is gaining popularity. The presented study compares complications and outcomes of unilateral and bilateral DIEP free-flap breast reconstructions using the largest database available in Europe. METHODS Female breast cancer patients (n = 3926) receiving DIEP flap breast reconstructions (n = 4577 free flaps) at 22 different centers were included in this study. Free flaps were stratified into two groups: a unilateral- (UL) and a bilateral- (BL) breast reconstruction group. Groups were compared with regard to surgical complications and free flap outcome. RESULTS Mean operative time was significantly longer in the BL group (UL: 285.2 ± 107.7 vs. BL: 399.1 ± 136.8 min; p < 0.001). Mean ischemia time was comparable between groups (p = 0.741). There was no significant difference with regard to total (UL 1.8% vs. BL 2.6%, p = 0.081) or partial flap loss (UL 1.2% vs. BL 0.9%, p = 0.45) between both groups. Rates of venous or arterial thrombosis were comparable between both groups (venous: UL 2.9% vs. BL 2.2%, p = 0.189; arterial: UL 1.8% vs. BL 1.2%, p = 0.182). However, significantly higher rates of hematoma at the donor and recipient site were observed in the UL group (donor site: UL 1.1% vs. BL 0.1%, p = 0.001; recipient site UL 3.9% vs. BL 1.7%, p < 0.001). CONCLUSIONS The data underline the feasibility of bilateral DIEP flap reconstruction, when performed in a setting of specialized centers.

Abstract
INTRODUCTION To avoid mesh-related complications, autologous transobturator-tape (a-TOT) technique is a viable option in stress urinary incontinence (SUI) surgery. The method differs from TOT and retropubic tape (RT) in the usage of autologous tissue. We hypothesized that a-TOT improves female sexual dysfunction (FSD) more than TOT and RT. METHODS This is a retrospective cohort study. Patients who underwent a-TOT, TOT, and RT surgeries were surveyed regarding the cure of SUI, complications, and FSD parameters. The groups were compared according to baseline and postoperative data. RESULTS A-TOT, TOT, and RT groups included 37, 69, and 36 patients, respectively. The median follow-up time was 19 months. The groups were similar in terms of preoperative characteristics. The objective cure, subjective cure, and overall complication rates were comparable among the groups (p > 0.05). A-TOT group had significant improvements in mean female sexual function index (FSFI) scores, TOT group deteriorated, and RT group remained stable (p = 0.001, p = 0.001, and p = 0.226, respectively). The postoperative mean total FSFI scores were 25.73 ± 2.46, 23.17 ± 3.35, and 21.53 ± 2.47 for the a-TOT, TOT, and RT groups, respectively. The a-TOT group had better results than the TOT and RT groups (p < 0.05 and p < 0.05), and besides, the difference between the TOT and RT groups was statistically significant (p < 0.05). According to percentage changes in domain scores following the operations, the a-TOT group had significantly better results in desire, arousal, lubrication, satisfaction, and pain domains than the TOT group (p < 0.05) as well as better desire, arousal, and pain domains (p < 0.05) than the RT group. DISCUSSION/CONCLUSIONS Besides comparable outcomes in SUI treatment, the a-TOT technique provides improvements in female sexual functions while TOT worsens and RT does not change. Favorable outcomes in sexual functions caused by improvements in desire, arousal, satisfaction, and pain domains are observed following the a-TOT technique.

Abstract
BACKGROUND Repair of the absence of the whole or major parts of pulmonary arteries is a challenge, and the choice of conduit material to reconstruct the pulmonary arteries is under dispute. We used the autologous innominate vein to construct pulmonary arteries. CASE PRESENTATION L We present a novel technique using the autologous innominate vein as a free graft in a 6-month-old infant with pulmonary atresia and absence of central pulmonary arteries. Double ductus arteriosus were the only source of perfusion of the lungs. The innominate vein was substituted for the central pulmonary artery between the two lung hila. Total repair by using Contegra graft was performed 9 months later. The patient has been followed for 5 years. CONCLUSIONS The autologous innominate vein could be used as inter-hilar pulmonary arteries with no calcification and fibrosis in 5-year follow-up.

Abstract
BACKGROUND Pulmonary complications are common among hematologic stem cell transplant (HSCT) recipients. Their evaluation can be pursued through bronchoscopy with bronchoalveolar lavage (BAL) and a variety of available noninvasive studies, which include newer molecular markers for detecting a variety of infectious agents. OBJECTIVE The objective of this study is to evaluate the diagnostic yield of BAL among HSCT patients relative to the yield of noninvasive testing. METHOD This is a retrospective analysis of HSCT recipients who underwent both BAL and noninvasive testing at a cancer center in 2013 and 2014. RESULTS There were 210 diagnostic results among 98 HSCT recipients. There were 84 unique findings on noninvasive testing that were not evident on BAL, and 36 unique findings on BAL that were not evident on noninvasive testing. Noninvasive testing tended to yield bacterial and viral infections more commonly, while BAL yielded mycobacterial isolates more commonly. CONCLUSION While both noninvasive testing and BAL are helpful in this population, each appeared more precise than the other with individual lung diseases. Bronchoscopy with BAL and noninvasive testing should be considered complementary strategies in the workup of pulmonary complications among HSCT patients.

Abstract
Mobilization failure in patients is a major therapeutic concern which makes subsequent ASCT impossible. A new growth factor called Plerixafor (Mozobil®) developed by the pharmaceutical industry (Sanofi-aventis, France), is a chemoreceptor antagonist, CXCR4 type, which disrupts the interaction of SDFI and CXCR4, thereby enhancing the effect of G-CSF mobilization and is especially indicated for mobilization failure. Currently, there is a generic of plerixafor developed by the pharmaceutical industry (Hetero Drugs Ltd, India). The brand name of this medicine is Mozifor®. The objective of this study was to evaluate if generic plerixafor has the same efficacy and safety as originator plerixafor when used with G-CSF in the mobilization of PBSCs for autologous ASCT in multiple myeloma (MM) and lymphoma failure patients. The 32 patients received plerixafor were divided in two groups. The first group concerns the 11 consecutive patients prospectively received generic plerixafor (Mozifor®) in the period between January to July 2020. These were compared with a retrospective control cohort (second group n = 21) who had been treated between 2009 and 2019 with originator plerixafor (Mozobil®). For the Mozifor® group, the mean CD34+ was 4.54x106/kg(1.56-6.79), the median time to achieve an absolute neutrophil count >0.5 G/L was 13 days (range: 8-21). The median time to self-sustained platelet count >20 G/L was 15 days (range: 8-24). For the Mozobil® group, the mean CD34+ was 3.1x106/kg (0.56-8.91) (p=0.86), the median time to achieve an absolute neutrophil count >0.5 G/L was 10 days (range 7-23). The median time to self-sustained platelet count >20 G/L was 13 days (range: 7-29). Our study showed that the generic of plerixafor was practically identical to that of the originator (Mozobil®) with no significant difference (p = 0.52). This study demonstrates the safety and feasibility of mobilization PBSC with generic plerixafor in ASCT in MM and lymphoma. Although these outcomes are encouraging, prospective comparison with other traditional auto-HCT regimens used for patients with MM and lymphoma is warranted.

Abstract
Breast reconstruction and oncoplastic surgery have become an important part of breast cancer care. The use of autologous breast reconstruction (ABR) has evolved significantly with advances in microsurgery, aiming to reduce donor site complications and improve cosmesis. For years, immediate-ABR was considered a contraindication if postmastectomy irradiation (PMRT) was planned. As a result of de-escalation of axillary surgery the indication of PMRT are increasing along-side with observations that PMRT in the setting of ABR is not contraindicated. Surgical techniques may result in different amount and areas of breast residual glandular tissue and patient selection is important to reduce potential residual disease. Meticulus radiation planning is important to potentially reduce complications without compromising oncologic outcomes. Surgical techniques change constantly in aim to improve aesthetic results but should most importantly maintain priority to the oncological indications. By multidisciplinary team work with a comprehensive understanding of each discipline, we can preserve the accomplishments of breast surgery in the setting of PMRT, without compromising disease control.

Abstract
BACKGROUND Breast reconstruction with implants has proven serious complications, mostly in patients who have undergone radiotherapy. In these cases, autologous reconstruction is the technique of choice. OBJECTIVES To study if breast reconstruction using latissimus dorsi and immediate fat grafting (LIFG) is a widely applicable technique for those cases in which an autologous reconstruction is desirable, but the use of microsurgical perforator flaps is not available. METHODS Data of 95 consecutive breast reconstructions from May 2014 to December 2018 were prospectively collected. All patients included in the study had a minimum follow-up of one year after completion of the reconstructive process. RESULTS The mean age of the patients was 48.57 years with an average follow-up of 20.65 months. The mean number of surgeries per patient was 1.61. In 47.4% of the cases, only LIFG surgery was required to accomplish the reconstructive process. The mean volume of fat graft used was 416.00 ± 145.79 cc. Relevant statistically significant differences in the volume of graft were found regarding the use of previous radiotherapy and the timing of reconstruction. Radiological fat necrosis nodes were the main complication (15.8%). However, their presence was significantly lower if no additional fat grafting sessions were necessary, though, unexpectedly, no relation was found in relation to the total amount of fat graft needed. CONCLUSIONS LIFG has proved to be a safe and reliable method for total autologous breast reconstruction. Even when a medium to large size is required, a large volume of fat graft is accepted; thus, excellent results can be obtained. It is an interesting alternative for breast reconstruction, in addition to abdominal perforator flaps.

Abstract
Introduction Breast cancer stands out as the second most common cancer in the world with incidence 35.1% of all malignancies among females in Egypt. Fluid build-up after breast surgery is still the most annoying complication which leads to worse outcome. We aimed to evaluate whether autologous fibrin glue might lessen the formation of seroma following modified radical mastectomy. Methods This was a randomized controlled trial designed to configure the effect of autologous fibrin glue given in the study group using the drain in comparison to a control group who received the drain only; seroma volume was calculated every 24 h. For all of the cases. The drains were removed when the daily drainage was less than 30 ml for 3 consecutive days. Results We recruited 30 patients to each of the two groups. Age, pathology, breast cancer stage, number of lymph nodes and tumour size did not differ significantly between groups. A comparison of the median days to drain removal showed 8 days reduction in median days to drain removal compared in the intervention group (7 days) than the control (15 days). The patients in the fibrin glue group had a significantly lower cumulative drain output volume (mean ± SD of 505,6 ± 209,3 ml) than those in the control group (1674.1 ± 1 373,8 ml). Conclusions Autologous fibrin glue significantly decrease seroma formation post-modified radical mastectomy. Seroma is the most annoying complication after breast cancer surgery. Fibrin glue is an adhesive agent has been associated with reduction in the fluid build-up post mastectomy. Autologous Fibrin Glue is easily prepared and safe agent. The usage of Autologous fibrin glue help in short hospital stay after mastectomy. This is the first randomized clinical intervention to use fibrin glue from autologous nature to reduce seroma formation after MRM.

Abstract
We previously reported the effectiveness of autologous mesenchymal stromal cells (MSCs) for the treatment of aortic aneurysm (AA), mediated mainly by these cells' anti-inflammatory properties. In this study, we investigate whether the therapeutic effects of allogeneic MSCs on AA are the same as those of autologous MSCs. To examine the immune response to allogeneic MSCs, C57BL/6 lymphocytes were co-cultured with BALB/c MSCs for 5 days in vitro. Apolipoprotein E-deficient C57BL/6 mice with AA induced by angiotensin II were randomly divided into three groups defined by the following intravenous injections: (i) 0.2 ml of saline (n = 10, group S) as a control, (ii) 1 × 106 autologous MSCs (isolated from C57BL/6, n = 10, group Au) and (iii) 1 × 106 allogeneic MSCs (isolated from BALB/c, n = 10, group Al). Two weeks after injection, aortic diameters were measured, along with enzymatic activities of MMP-2 and MMP-9 and cytokine concentrations in AAs. Neither allogenic (BALB/c) MSCs nor autologous (C57BL/6) MSCs accelerated the proliferation of lymphocytes obtained from C57BL/6. Compared with group S, groups Au and Al had significantly shorter aortic diameters (group S vs Au vs Al; 2.29 vs 1.40 vs 1.36 mm, respectively, p < 0.01), reduced MMP-2 and MMP-9 activities, downregulated IL-6 and MCP-1 and upregulated expression of IGF-1 and TIMP-2. There were no differences in these results between groups Au and Al. Thus, our study suggests that treatment with allogeneic MSCs improves chronic inflammation and reduced aortic dilatation. These effects were equivalent to those of autologous MSCs in established mouse models of AA.

Abstract
PURPOSE OF REVIEW Numerous surgical techniques are available to treat osteochondral defects of the knee. The aim of this review is to analyse these procedures, including their methodology, outcomes and limitations, to create a treatment algorithm for optimal management. RECENT FINDINGS Osteochondral defects of the knee significantly alter the biomechanics of the joint. This can cause symptomatic and functional impairment as well as considerable risk of progressive joint degeneration. Surgical interventions aim to restore a congruent, durable joint surface providing symptomatic relief and reducing the risk of early arthritic changes. These methods include fixation, chondroplasty, microfracture, autologous matrix-induced chondrogenesis, autograft transplants, allograft transplants and autologous chondrocyte implantation. There is currently much debate as to which of these methods provides optimal treatment of osteochondral defects. The overall evidence supports the use of each technique depending on the individual characteristics of the lesion. New technologies provide exciting prospects; however, long-term outcomes for these are not yet available.

Abstract
Adult acute lymphoblastic leukemia/lymphoma (ALL/LBL) is a rare and heterogeneous malignancy characterized by uncontrolled proliferation of B or T cell precursor cells. Here, we retrospectively analyzed the outcome of early autologous stem cell transplantation in standard-risk patients in first complete remission (n=24) and of allogeneic transplantation in high and highest risk, and relapsed/refractory patients (n=35). The 10-year overall survival after autologous transplantation was 45%. The 10-year overall survival after allogeneic transplantation was 58%. The cumulative incidence of relapse was 29% after allogeneic and 67% after autologous transplantation. The cumulative incidence of non-relapse mortality was 0% after autologous and 12% after allogeneic transplantation. This retrospective single center analysis in a limited number of standard-risk patients clearly demonstrates that early autologous transplantation in first complete remission leads to an acceptable long-term outcome with a short overall treatment duration of less than 6 months compared with more than 2 years with conventional chemotherapy. More sensitive and standardized methods to detect minimal residual disease (MRD) will further help to identify those patients more accurately who are most likely to benefit from such a short and intensive treatment strategy (i.e., MRD negative standard-risk patients) or those who require early targeted therapy (e.g., blinatumomab) in case of MRD positivity. Early allogeneic transplantation results in long-term survival/cure in nearly two-thirds of all high and highest risk, and relapsed/refractory patients.

Abstract
PURPOSE This systematic review (SR) assessed the efficacy, safety and cost-effectiveness of cell-based therapy to manage limbal stem cell deficiency (LSCD), a sight-threatening orphan condition most frequently associated with severe chemical or thermal burns. LSCD has historically been treated by transplanting limbal tissue. In 1997, a new treatment, cultured limbal epithelial autografts, was described for unilateral LSCD. In cases of bilateral disease cultured autologous oral mucosa stem cells have been used. The relative efficacy of different cultured tissue procedures is unknown. METHODS A protocol was registered with PROSPERO (CRD42017081117). Searches were conducted in 14 databases and 6 conference websites. Two reviewers independently selected studies, conducted data extraction and assessed risk of bias. One reviewer extracted individual patient data (IPD); a second checked extracted data. Data were assessed to determine the feasibility of statistical analysis, with Bayesian synthesis used to estimate improvement achieved by different treatments. RESULTS Fifty-two studies were eligible for inclusion (1113 eyes); 41 studies (716 eyes) reported IPD. No evidence was identified on cost-effectiveness. This SR was unable to confirm that any of the types of ex vivo cultured stem cell transplants identified for LSCD treatment were statistically superior when assessed against the outcomes of interest. CONCLUSIONS We believe this SR is the first to include IPD analysis of LSCD data. There is no evidence for the superiority of any method of limbal stem cell transplant. Confirmation of the safety and efficacy of this treatment modality is challenging due to heterogeneity within and between the studies identified. Therefore, recommendations for future research are proposed.

Abstract
BACKGROUND Autologous hematopoietic stem cell transplantation (auto-HSCT) has become an effective treatment for a wide range of hematologic and non-hematologic diseases. Patients undergoing HSCT might require multiple platelets and red blood cell (RBC) transfusions during aplasia phase until engraftment, which could profoundly affect patients' conditions. Identification of risk factors associated with blood product requirements could help in decreasing transfusion-related complications. We evaluated the association of disease type, pre-transplant hemoglobin level, and pre-transplant platelet count with RBC/platelet transfusion requirement after auto-HSCT. METHODS In this retrospective study, 324 patients diagnosed with multiple myeloma (MM), Hodgkin disease (HD), and non-Hodgkin lymphoma (NHL) and underwent auto-HSCT were included. The associations of disease type, pre-transplant hemoglobin level, and platelet count with post-transplant packed cell and single-/random-donor platelet transfusions were evaluated. RESULTS Our study results illustrated that the higher pre-transplant hemoglobin level significantly decreased the post-HSCT requirement for packed cell (IRR=0.81, [CI: 9.73-0.90], P=0.0001), while the pre-transplant platelet showed no significant relationship with platelet requirement after HSCT. HD was associated with increment in packed cell (IRR=2.04, [CI: 1.35-3.08], P=0.001) and single donor platelet (IRR=1.39, [CI: 1.09-1.78], P=0.008) requirement after transplant. The trends showed that a higher platelet level led to a lower need for platelet transfusion. CONCLUSION Pre-transplant hemoglobin level could be valuable markers for predicting post-HSCT RBC requirements and might be beneficial for better management of transfusion requirements to minimize the transfusion-related complications. Patients with HD seem to be more prone to blood product requirements post-transplant.

Abstract
BACKGROUND Autism spectrum disorders [ASD] is a lifelong disability mainly affecting the development, communication, social interaction and behavior of an individual. Cell transplantation is emerging as a potential therapeutic strategy for ASD. Our previously published proof of concept study showed beneficial effects of cell transplantation in ASD. This study shows effect of cell transplantation in a larger sample size of ASD patients. METHODS 254 patients diagnosed with ASD on DSM V criteria were enrolled in this open label non-randomized study. The intervention included intrathecal transplantation of autologous bone marrow mononuclear cells and neurorehabilitation. On mean follow up of 7.50 months, percentage analysis was performed on all symptomatic changes. Changes in outcome measures, Indian Scale for Assessment of Autism [ISAA] and Childhood Autism Rating Scale [CARS], were analyzed statistically using Wilcoxon Signed-Rank Test. Comparative analysis of Positron Emission Tomography [PET CT] scan brain, performed before and 6 months after intervention, was done in 86 patients to monitor the outcome at cellular level. Change in the standardized uptake values was statistically evaluated using T-Test [P≤0.05]. RESULTS Improvements were observed in eye contact, attention and concentration, hyperactivity, sitting tolerance, social interaction, stereotypical behavior, aggressiveness, communication, speech, command following and self-stimulatory behavior. Statistically significant improvement was observed in scores of ISAA and CARS after intervention. A significantly better outcome of the intervention was found in patients at younger age and with shorter duration of disease [<5 years from time of diagnosis]. 86 patients who underwent a repeat PET CT scan showed improved brain metabolism after intervention in areas which correlated to the symptomatic changes. No major procedure related adverse events were recorded. However, 5 patients, with history of seizure and abnormal EEG, had an episode of seizure which was managed using medications. Outcome of intervention in these patients was not affected by seizures as improvements were observed in them. CONCLUSION The results of this study indicate that autologous bone marrow mononuclear cells in combination with neurorehabilitation are a safe and effective treatment modality for ASD. It improves the quality of life of patients and helps them to integrate in mainstream lifestyle.

Abstract
Background Osteoarthritis (OA) is progressive degenerative damage to articular cartilage. Current therapeutic options are reduced to control the OA-associated symptoms, leaving the degenerative changes to progress until a joint replacement becomes mandatory. Therefore, therapeutic alternatives are warranted to improve the patient’s quality of life. Cell-based therapy is a developing therapeutic modality, showing promising results in the regeneration of injured cartilage and reduction of on-going inflammation within the affected joint. The current retrospective chart review study was aimed to analyze changes in pain and mobility of subjects with OA after stromal vascular fraction (SVF) cell therapy. Methods Three hundred fifty subjects with hip and knee OA, treated with autologous SVF cells at the Malacky Hospital (Bratislava, Slovakia) in the period from 2015 to 2018, were included in the retrospective chart review study. Results Seven days after SVF cell therapy, 45.2% of subjects experienced improved pain levels and mobility. Three, 6, and 12 months after therapy, improvement in pain levels reached 75.3%, 84.4%, and 84.9%, and improvement in mobility reached 75.2%, 84.4%, and 84.9%. Conclusions Our study of 350 subjects with hip and knee OA showed a significant improvement in pain levels and mobility 3, 6, and 12 months compared to 7 days after autologous SVF cell administration. The treatment demonstrated a strong safety profile with no severe adverse events or complications reported. The results of the study are showing that SVF cell therapy was more effective in subjects with arthritis stage III compared to arthritis stages I, II, and IV.

Abstract
Background: Diabetic ulcers are a common morbidity associated with poorly controlled glycemic status. Most patients often have neuropathy and vasculopathy as the etiology behind such ulcers. These factors not only lead to poor wound healing but also nonhealing ulcers. Nonhealing ulcers pose therapeutic challenges as they are usually not amenable to be treated with simple wound care and hence require newer modalities to effectively cure this condition that leads to a plethora of poor health outcomes. This study was conducted to see the effect of autologous noncultured keratinocyte cell suspension in chronic nonhealing diabetic ulcers that failed to normal wound care. Material and Methods: It was an observational pilot study. A total of 05 patients with nonhealing ulcers, attending the tertiary care teaching hospital in North India, were included in the study. Inclusion criteria was type 2 DM with more than 5 years duration of diabetes mellitus and glycated hemoglobin (HbA1c) <9 g%. History was taken in detail; name, age, sex, address, duration of disease and various other treatments taken from outside were noted; and size of ulcer was recorded as per Proforma. Results: A total of 5 patients were enrolled in the study, three (60%) and two (40%) patients were male and female, respectively. Three (60%) patients were habitual for tobacco use. Mean age of patients was 45 ± 6.51 years. Mean duration of ulcers was 4.8 ± 1.48 months. Area of ulcers ranged from 31.2 to 122.2 cm2. Majority of cases, three (60%) of diabetic foot ulcers, were improved at 9–12 weeks and remaining two cases with large size of ulcer were healed at 13–16 weeks and 17–20 weeks, respectively. Majority (80%) of patients revealed >50% reduction in the size of ulcer within 2 weeks. Conclusion: Noncultured keratinocytes are useful in healing of nonhealing diabetic ulcer.

Abstract
To restore corneal transparency and vision loss after an injury on the ocular surface, the use of human stem cells from different origins has been recently proposed. Mesenchymal stem cells (MSCs) seem to be an appropriate adult source of autologous stem cells due to their accessibility, high proliferation rate, and multipotent capacity. In this work, we developed a simple culture system to prepare a graft based on a fibrin membrane seeded with human MSCs. A commercial kit, PRGF Endoret®, was used to prepare both, the growth factors used as culture media supplement and the fibrin membrane grafts. Adipose-derived MSCs (Ad-MSCs) were expanded, characterised by flow cytometry and their multilineage differentiation potential confirmed by inducing adipogenesis, osteogenesis and chondrogenesis. Ad-MSCs seeded on the fibrin membranes were grafted onto athymic mice showing good biocompatibility with no adverse reactions observed during the follow up period. These findings support the assumption that a system in which all the biological components (cells, grow factors and carrier) are autologous, could potentially be used for future ex vivo expansion of Ad-MSCs to treat ocular conditions such as an inflammatory milieu, traumatic scars and loss of the regenerative capacity of the corneal epithelium that compromise the quality of vision.

Abstract
Mastectomy may be performed to treat breast cancer or as a prophylactic approach in women with a high risk of developing breast cancer. In addition, mastectomies may be performed with or without reconstruction. Reconstruction approaches differ and may be autologous, involving a transfer of tissue (skin, subcutaneous fat, and muscle) from other parts of the body to the chest wall. Reconstruction may also involve implants. Implant reconstruction may occur as a single procedure or as multistep procedures with initial use of an adjustable tissue expander allowing the mastectomy tissues to be stretched without compromising blood supply. Ultimately, a full-volume implant will be placed. Reconstructions with a combination of autologous and implant reconstruction may also be performed. Other techniques such as autologous fat grafting may be used to refine both implant and flap-based reconstruction. This review of imaging in the setting of mastectomy with or without reconstruction summarizes the literature and makes recommendations based on available evidence. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Abstract
Background Parastomal hernia is a common complication of stoma formation and the methods of repair available today are unsatisfactory with high recurrence and complication rates. To improve outcome after surgical repair of parastomal hernia, a surgical method using autologous full-thickness skin grafts as intraperitoneal reinforcement has been developed. The purpose of this study was to evaluate the feasibility of this novel surgical technique in the repair of parastomal hernia. Methods A pilot study was conducted between January 2018 and June 2019 on four patients with symptomatic parastomal hernia. They had a laparotomy with suture reduction of the hernia and reinforcement of the abdominal wall with autologous full-thickness skin. They were then monitored for at least 1 year postoperatively for technique-related complications and recurrence. Results No major technique-related complications were noted during the follow-up Two patients developed a recurrent parastomal hernia at the long term follow-up. The other two had no recurrence. Conclusions Autologous full-thickness skin graft as reinforcement in parastomal hernia repair is feasible and should be evaluated in a larger clinical trial.

Abstract
BACKGROUND Autologous hematopoietic stem cell transplant (autoHCT) is a mainstay of treatment for multiple myeloma and non-Hodgkin lymphoma but is underutilized in older adults. We investigated the association of vulnerabilities identified by a geriatric assessment (GA)-guided multidisciplinary clinic (MDC) on the receipt of autoHCT and evaluated its ability to predict outcomes in older autoHCT candidates. METHODS Patients 50+ years received GA-informed optimization recommendations: 'decline' if unlikely to realize benefits of autoHCT, 'defer' if optimization necessary before autoHCT, and 'proceed' if autoHCT could proceed without delay. We compared characteristics and outcomes of autoHCT recipients (n = 62) to non-autoHCT patients (n = 29) and evaluated GA deficits on outcomes. RESULTS 91 patients were evaluated; the MDC recommendation was 'decline' for 5 (6%), 'defer' for 25 (27%), and 'proceed' for 61 (67%). AutoHCT recipients had fewer GA-rated impairments relative to non-autoHCT patients, as did patients with a 'proceed' recommendation relative to 'defer'. Among autoHCT recipients, 1-year and 3-year non-relapse morality (NRM) was 0% and 5%, and there was no difference in length of hospitalization, readmission rate, or mortality after transplant by MDC recommendation. Frail grip strength and poor performance status were associated with inferior post-autoHCT progression-free survival and overall survival. CONCLUSIONS Patients pursuing autoHCT after MDC-directed optimization achieved excellent outcomes, including patients deferred but ultimately receiving autoHCT. GA-identified functional deficits, especially frail grip strength, may improve risk stratification in older autoHCT candidates. Employing a GA earlier in the disease trajectory to inform early referral to an MDC may increase autoHCT safety and utilization in older patients.

Abstract
Closure of wounds with tissue adhesives has many advantages over sutures, but existing synthetic adhesives are toxic and have poor workability. Blood-derived adhesives display complete resorption but have adhesion too weak for reliable wound dressings. We propose a semi-synthetic design that combines the positive attributes of synthetic and blood-derived tissue adhesives. PAMAM-g-diazirine (PDz) is a rapidly gelling bioadhesive miscible in both aqueous and organic solvents. PDz blended with platelet-rich plasma (PRP) forms PDz/PRP composite, a semi-synthetic formulation that combines PDz's wet tissue adhesion with PRP's potent wound healing properties. Light-activated PDz/PRP bioadhesive composite has similar elasticity to soft tissues and behaves as an induced hemostat-an unmet clinical need for rapid wound dressings. PDz/PRP composite applied to in-vivo full-thickness wounds observed a 25% reduction in inflammation, as assessed by the host-cell response.
